In recent years, relevant departments in China have repeatedly issued policy documents to promote the intelligent construction of coal mines, requiring the integration of intelligent technology with the coal in-dustry. As a popular intelligent technology, autonomous driving has been considered an important means of intelligent construction in coal mines. Autonomous driving includes several major processes, including environmental perception, location mapping, planning and decision-making, and automatic control. Among them, location mapping is the premise and foundation of each process. SLAM is currently the mainstream positioning and mapping technology, which has been studied for many years for ground and indoor envi-ronments and has been applied in multiple fields; However, research on complex mining environments is still in its early stages and has broad development prospects. In order to promote the development of SLAM technology in the field of unmanned driving in mines, the principles of SLAM technology, mature SLAM solutions, current research status of mine SLAM, and future development trends of mine SLAM were dis-cussed. Firstly, the principle and framework of SLAM technology were clarified; Afterwards, as the research and application of SLAM technology in the field of unmanned mining can draw on mature ground tech-nology solutions, representative SLAM solutions on the ground were investigated. Based on the sensors used, they were classified, analyzed, and summarized from three aspects: vision, laser, and multi-sensor fusion. The conclusion was drawn that "multi-sensor fusion is an important means to optimize SLAM technology"; Furthermore, the current research status of mining SLAM technology was explored, and the applicability and research value of three SLAM schemes, namely vision, laser, and multi-sensor fusion, in underground coal mines and open-pit mines were analyzed. The conclusion was drawn that "multi-sensor fusion SLAM is the best research scheme in the field of underground coal mines" and "the research value of SLAM tech-nology in open-pit mines is not high"; Finally, based on the previous analysis, combined with the devel-opment trends of artificial intelligence and hardware, it is proposed that SLAM technology in the field of unmanned mining should develop towards multi-sensor fusion, solid-state, and intelligent direction in the future.
